If you are looking to stay low end the Lee sizers work really well and will seat the gas checks also,I use them a lot. Lee alox tumble lube work just fine also and a bottle of it comes with every sizer you order.
I would get a minimum ten pound pot lead goes really fast when you get to casting.
I also use the Lee molds and the 158 gr SWCGC shoots really well out of my .357s I like the six cavity molds, I use the 180gr mold for my.357 maxies.
I use straight WWs mostly and genrally have no problems at all. I've also learned that some off them ugly looking bullets with wrinkles and such still shoot well as long as they have a good base.
I really enjoy casting and all the game I've taken in the last four or five years has been with bullets I cast and loaded myself, Good luck.
